2. How to change the oil of lawn mower?

The oil of the new lawn mower should be changed after 5 hours of operation for the first time, and the oil should be changed every 30-50 hours after use.

To change the oil, you can drain the oil in the oil drain hole of the oil pan at the lower part of the cutter head, or open the oil filler port and tilt the machine to the left to drain the oil (the air filter must be at the upper part). Regardless of how to put it, you should immediately drain the oil after removing the ignition wire of the spark plug and restore it immediately after the engine is stopped, and refill the appropriate engine oil to the specified scale.

Note: The discharged waste engine oil should be kept well and handed over to the waste oil recycler to avoid polluting the environment.

3. How to clean the air filter of lawn mower?

The foam filter element is cleaned every 25 hours, and the dust should be more frequent.

The foam filter element is cleaned with kerosene or washing liquid and water, squeezed to dry, and then soaked in oil, squeezed out the excess oil to install. If it is printed with "DON NOT OIL", there is no need to add oil.

The paper filter element is cleaned every 25 hours, more frequently when the dust is large.

The front filter with a front air filter is cleaned every 25 hours, and the paper core is cleaned every 100 hours. It should be more frequent when the dust is large.

The cleaning of the front air filter is the same as the foam filter element.

The paper filter element should be tapped on a flat surface. If it is very dirty, a should be replaced or cleaned in low or non-foaming detergent and warm water solution; b rinse thoroughly with running water from inside and outside until the water is clean; c stand upright and air dry.

Note: Petroleum solvents such as kerosene cannot be used to clean the paper core. Because it may cause the paper core to deteriorate, do not put engine oil on the paper core, and do not use compressed air to clean or dry the paper core.
